Introduction to LADSPA

LADSPA is the "Linux Audio Developer's Simple Programming API," whose goal is to provide a versatile audio plug-in capability similar to VST. It is deliberately designed to be extremely simple. As described on the project web site, "The 'S' in 'LADSPA' is meant seriously." The LADSPA development "framework" consists of just one C header file, plus the development tools you will build here.

Project Homepage: http://www.ladspa.org

Common Build Instructions

The build system is not autotools based. However, the makefile is so simple that you will probably want to simply edit and run the makefile manually.

Build the package 

cd src
edit makefile
    INSTALL_PLUGINS_DIR = ...
    INSTALL_INCLUDE_DIR = ...
    INSTALL_BINARY_DIR = ...
make

Install the package 

make install
create multiarch wrappers for all 3 binaries

Here is a script that automates this process, while also adding DESTDIR capability, which is missing in the original makefile: 

cat > build.sh << "EOF"
: ${CLFS_LIB32:="lib"}
: ${CLFS_LIBN32:="lib32"}
: ${CLFS_LIB64:="lib64"}
: ${CLFS_LIB:="lib"}

eval CLFS_LIB='$'CLFS_LIB${USE_ARCH} &&
eval BUILD='$'BUILD${USE_ARCH} &&
eval LD_BUILD='$'LD_BUILD${USE_ARCH} &&

pushd src &&

if [ -e makefile-original ]; then

    make clean
    mv -f -v makefile-original makefile

fi

CLFS_LIB=${CLFS_LIB} \
sed -i-original \
    -e 's/$(INSTALL_PLUGINS_DIR)/$(DESTDIR)$(INSTALL_PLUGINS_DIR)/g' \
    -e 's/$(INSTALL_INCLUDE_DIR)/$(DESTDIR)$(INSTALL_INCLUDE_DIR)/g' \
    -e 's/$(INSTALL_BINARY_DIR)/$(DESTDIR)$(INSTALL_BINARY_DIR)/g' \
    -e "s|/usr/local|/usr|g" \
    -e "s|/lib/|/${CLFS_LIB}/|g" \
    makefile &&

make \
    DESTDIR=${DESTDIR} \
    CC="gcc ${BUILD}" \
    CPP="g++ ${BUILD}" \
    LD="ld ${LD_BUILD}" &&

make install &&

if [ "$USE_ARCH" != "" ]; then

    mv -v ${DESTDIR}/usr/bin/analyseplugin ${DESTDIR}/usr/bin/analyseplugin-${USE_ARCH} &&
    mv -v ${DESTDIR}/usr/bin/applyplugin ${DESTDIR}/usr/bin/applyplugin-${USE_ARCH} &&
    mv -v ${DESTDIR}/usr/bin/listplugins ${DESTDIR}/usr/bin/listplugins-${USE_ARCH}

fi

if [ "${USE_ARCH}" == "64" ]; then

    ln -sfv multiarch_wrapper ${DESTDIR}/usr/bin/analyseplugin &&
    ln -sfv multiarch_wrapper ${DESTDIR}/usr/bin/applyplugin &&
    ln -sfv multiarch_wrapper ${DESTDIR}/usr/bin/listplugins

fi

popd
EOF

chmod +x build.sh


Non-Multilib

Compile and install the package: 

./build.sh

Multilib

32Bit

Compile and install the package: 

USE_ARCH=32 ./build.sh

N32

Compile and install the package:

To Do: (Please Contribute. It is intended that "USE_ARCH=N32 ./build.sh" should work.)

64Bit

Compile and install the package: 

USE_ARCH=64 ./build.sh

Configuring

An environment variable, LADSPA_PATH, is required. 

cat > /etc/profile.d/50-ladspa.sh << "EOF"
export LADSPA_PATH=/usr/lib/ladspa:/usr/lib32/ladspa:/usr/lib64/ladspa

Contents

Installed Directories: /usr/lib{,32,64}/ladspa
Installed Programs: analyseplugin, applyplugin, listplugins
Installed Libraries: amp.so, delay.so, filter.so, noise.so, sine.so

Short Descriptions

analyseplugin, applyplugin, listplugins are tools for inspecting and testing ladspa plug-ins.
amp.so, delay.so, filter.so, noise.so, sine.so are sample plug-ins
/usr/include/ladspa.h is the API, in its entirety. The comments in this (well-commented) header file comprise the API documentation.
